Abstract: | The Borg Scale, widely used to measure perceptions of exercise, has not been validated for use during recovery. Heart rate was used as the validity criterion. 11 untrained men and 10 untrained women were run to exhaustion on a treadmill. Heart rate and recovery ratings were obtained at :15, :45, 1:15, 1:45, 2:30, 3:30 and 4:30 min. following exercise. No significant differences were observed between sexes for both heart rate and recovery ratings. Trend analysis showed recovery ratings to be linear between :45 and at 4:30 while heart rate is best described by two linear trends with a break point at 2:30. Percent recovery was significantly faster for recovery ratings at :45, 1:15, 1:45 and 4:30. Heart rate and recovery ratings were not significantly correlated at any time point. A perceptual scale should be designed which more closely approximates metabolic response during recovery. |
